Number	Title	Issue Date
6275416	Pulse generator circuit, particularly for non-volatile memories A pulse generator circuit for non-volatile memories, is disclosed, including a circuit for determining the instant at which a pulse for incrementing a counter of the memory is generated and generating an increment pulse duration start signal; a circuit fo...	08/14/2001
4205338	Disc recording tracking system A prerecorded track on a disc is automatically tracked resulting in a radial tracking signal. Components of this signal are stored during a prerecording interval. During recording these stored components are used to produce a restored radial tracking sign...	05/27/1980
3936883	Magnetic bubble read/write head Magnetic bubbles are employed to write and read digitized signals of audio, video and digital data in a magnetic medium, while circumventing the problems associated with high linear tape speed or rotary head motion. Writing is accomplished via the interac...	02/03/1976
